+       tristate "Overlay filesystem support"
+       help
+         An overlay filesystem combines two filesystems - an 'upper' filesystem
+         and a 'lower' filesystem.  When a name exists in both filesystems, the
+         object in the 'upper' filesystem is visible while the object in the
+         'lower' filesystem is either hidden or, in the case of directories,
+         merged with the 'upper' object.
